The basisphcnoid presents on its dorsal or cerebral 

 surface the sella turcica, or pituitary fossa, which lodges 

 the pituitary body of the brain (Fig. 90). The posterior 

 boundary of this fossa is the clinoid plate, and its lateral 

 projections are the posterior clinoid processes. On each 

 side of the basisphenoid there extends dorsally in a
